Key Considerations When Choosing a Window Contractor

When embarking on a window replacement or installation project, it is important to assess several critical factors before selecting a contractor:

• Installation Practices: Proper installation is crucial for performance and longevity. Ask about the installation methods used, whether installers are factory-trained, and if the company follows manufacturer guidelines.
• Warranties and Service: Comprehensive warranties on both products and labor provide peace of mind. Understand what is covered and for how long.
• Customer Reviews and References: Check online reviews, ratings with the Better Business Bureau, and ask for references from past clients to gauge satisfaction and reliability.
• Energy Efficiency Expertise: Contractors should be knowledgeable about ENERGY STAR ratings and local energy codes, and able to recommend products that can reduce energy costs.
